Resumen:
The persistence of coherence of a superfluid flux qubits in presence of an ensemble of electrons is analyzed. The time evolution of the system is solved exactly. The appearance of squeezing in the qubit sector is studied by computing the entropy-squeezing parameter. We analyze the time evolution of the Wigner Function of the reduced density matrix of the qubits in order to determine the rate of decoherence induced by the coupling with the electrons. We found that the rate of induced decoherence may be reduced, depending on the interaction proposed.
